The series, which will air on Wednesdays at 8:00-9:00 p.m., stars Stephen Amell as Oliver Queen, Colin Donnell as Tommy, Katie Cassidy as Laurel Lance, David Ramsey as John Diggle, Willa Holland as Thea Queen, with Susanna Thompson as Moira Queen and Paul Blackthorne as Detective Quentin Lance.

The series has promoted Manu Bennett to series regular for its recently announced second season, The Hollywood Reporter has learned exclusively.

On the network's adaptation of DC Comics' long-running title, Bennett plays Slade Wilson -- who in the comics ultimately becomes Arrow's villain Deathstroke. Producers have been cagey if Bennett would follow his comic book counterpart and transform into the famed villain, featuring multiple Deathstrokes during its freshman run.
Exec producers Greg Berlanti, Andrew Kreisberg and Marc Guggenheim have thus far written Slade as an ally to Stephen Amell's Oliver, appearing in Arrow's flashbacks to their time on the island.

Bennett joins Colton Haynes (Roy Harper) and Emily Bett Rickards (Ollie's IT whiz Felicity Smoak) as series regulars for Arrow's second season. He's currently wrapping the third and final season of Starz's Spartacus, where he plays Crixus. Repped by Sanders Armstrong Caserta Management, Bennett also stars as Azog in all three Hobbit films.
